BEND RADIUS
Q: Because UPP® is semi-rigid, what bend radius is possible during installation?
A: This is largely temperature dependent, but in general you may use these values for single or double wall UPP® delivered as coils:
50 mm
63 mm
90 mm
110 mm
Warm Weather
15 x Ø
80 cm
1m
1.5 m

INTERSTITIAL VOLUME
When using leak detection equipment it is often necessary to know the interstitial volume of double wall pipes to decide the
amount of compressed gas or type of pumped detection unit required. Below are the volumes per metre of UPP® pipework.
